To celebrate my calculator app PCalc turning 30 today, I've written up all the history I can still remember:

pcalc.com/thirty

There's also a rare 30%-off sale, which runs until midnight tonight, PST.

Mac:
apps.apple.com/us/app/pcalc/id

iOS:
apps.apple.com/us/app/pcalc-th

A big thanks to everybody who has used PCalc during the last three decades!

@jamesthomson I want to hear some of those budding Jean Michel Jarre tracks.

@jamesthomson look, all I’m saying is a lot of the essential UI paradigms are already in place for “Synth by PCalc”
